Title: Tool carrier drive for programmed machine tool - has carrier and spindle alternately locked and released
IPC: B23B19/00
Filed: 1973-12-21
Abstract: The spindle (1) is fitted into a casing (8) which can be moved in relation to the machine (4) by passing hydraulic fluid onto one side of a built in hydraulic piston (20) flange (21) through line (23). This disengages two sets of teeth (18, 19) and movement is imparted by rotating the intermediate gears (11, 14, 15) of a gear train, keeping the pinion (10) on the spindle (1) blocked (25, 27).

Patent FR-2266134-A1 (FR)
Title: Cross flow water cooling tower - has concentric inlet troughs with adjustable flow restrictors on inner troughs
IPC: F28C1/04
Filed: 1974-03-29
Abstract: A tower to generate air flow rises above a base containing a direct contact cooling surface block. A peripheral louvre round and the base admits cooling air horizontally and water flows down vertically from distributing troughs which run concentrically round the bottom of the tower. One set of troughs runs around one semicircle from the water inlet and meets another set of troughs running round the other semicircle. Adjustable sliding vanes can restrict or totally stop the flow of water to the inner troughs concentrating all the flow in the outermost trough. This raises the temperature of the water at the entry to the cooling surfaces and prevents formation of ice in cold weather.

Title: Multipath resistor network heating plate - has redundancy provided by three branches for each resistor node
IPC: H05B3/84
Filed: 1975-03-10
Abstract: The heating plate uses insulating glass or ceramic material as a base (1) on which may be printed or laid a network of resistive lines arranged such that failure of any particular section does not seriously impair the functioning of the heater, i.e. there is some element of redundancy. Input points at the extreme ends of the plate feed two conductors (4) with parallel branched equispaced resistive paths which again branch off parallel to the heater side and then return again to form closed loops. The shape of the loop may be varied providing that each junction point (5) is reached by at least three electrical paths.

Title: Combined tub capping and punch cutting machine - for applying printed covers to thermoformed containers
Inventor: WAWRZYNIAK ALAIN
IPC: B29C51/44
Filed: 1975-03-14
Abstract: Equipment for capping and isolating thermoformed containers is described. Two independent drive systems are used to advance the web of containers and the capping film to a combined heat sealing and cutting unit. successive containers and (selected) portions of cover film are stopped in superimposed positions, clamped but sepd. vertically. A jack severs and lifts the container plus a peripheral flange which is then welded to the cover film. The sealed pack is then punched out downwards severing the cover film border and isolating the pack. Used esp. for sealing packs with preprinted covers designs to be precisely located on top of the pack. Alignment problems and cycle times are reduced by combining the welding and cutting operations at one unit station.

Title: Composite sheet formed by feeding liq. foam between two non-woven webs - and applying rigid panels to webs so foam adheres to them
IPC: B29C44/30
Filed: 1975-04-09
Abstract: A composite sheet matl. for e.g. building etc. is formed by advancing a lower porous non-woven web on a series of parallel cords and applying a layer of liq. foam matl. from an application. A second non-woven web is applied to the layer of foam matl. and the assembly passes through a calibrating device which smooths out the foam matl. to an even thickness. The foam matl. begins to gel and to penetrate the non woven webs and rigid panels advanced on conveyors are applied to respective surfaces of the webs so that the foam which has penetrated bonds them to the webs. As the resulting composite sheet is advanced the foam completely solidifies. The composite sheet material can be produced with a completely uniform thickness.

Title: Out of sync film editing method - synchronises sound and picture then displaces them out of sync. again after completion of editing
IPC: G03B31/02
Filed: 1975-05-16
Abstract: A film editing system is for film with its round and image tracks, out of synchronism. The image and round recordings are displaced so as to synchronise them, and editing then follows in known fashion as for a silent film. Afterwards the synchronised recording sounds are shifted out of synchronism with respect to the image. The sound recordings are displaced to another part of the same sound track, or to another track on the film, the sounds being displaced whilst running the film through a recorded sound reading unit (T1, T2), an erasing unit (T3) and a sound recording unit (T1, T2). Whilst the film is being run through these units, a film path is established between the reading and recording units, corresponding to the sound image shift. A transfer liaison is also established with the recording unit for the sounds read at the reading unit.

Title: Through-connector for insulating wall - has cable clamp passing through wall from one side and contact on other side
Inventor: THIBAUT JULES
IPC: H01F27/04
Filed: 1975-11-14
Abstract: The through-connector, for e.g. a transformer regulator, consists of a clamping part that presses a cable (5) against a locked metal cylinder that passes through the insulating wall (1) to a contact on the opposite side. A bolt (25) presses the cable onto the surface of the cylinder (10). The cylinder has a circular head with a locking pin (15) that engages in a hole (4) in the insulating wall, thereby preventing the cylinder from rotating or otherwise moving as the bolt is tightened. The contact (32) on the opposite side of the wall is fixed by a stud (33) passing axial into the other face of the cylinder. The advantage lies in its simple assembly.

Title: Web folding device - which comprises roller nip through which web passes and folding arm which forces a fold in the web to enter a second nip
IPC: B65H45/18
Filed: 1976-01-20
Abstract: A web folding devices comprises a feed conveyor from which the web is advanced by a selector surface (1) through a first nip between first and second rollers rotating in opposite direction. After the web has advanced a pre-determined distance through the first nip onto a support platform a folding arm acts on the web between the first nip and the platform and forms a fold which it forces into a second nip formed between the second roller and a third roller rotating in the opposite direction to the second roller. The line joining the centres of the second roller and the third roller forms an angle of 20-30 degrees (pref. 24 degrees) with the horizontal. The device folds webs quicker than devices using folding plates and eliminates manula operations.

Title: Digital clock time display - with pinions on same centreline engaging one minute, ten minutes, and hour wheel gears
IPC: G04C17/00
Filed: 1976-04-12
Abstract: The time display of a digital clock uses less components for the stepper mechanism so that a less expensive design is combined with smaller overall dimensions. This mechanism has a drive pinion (18) which is integral with a shaft on which a second drive pinion (20) can rotate freely. The first pinion (18) mates with a toothed rim on the periphery of the one-minute drum (16) and with a toothed rim on the periphery of the ten minutes drum (19). The second pinion (20) mates both with another toothed rim on the drum (19) and with a toothed rim on the hour drum (21). The five time display cards on the drum (16) are turned over by a C-shaped recess in the housing. The gear ratio for the pinion (18) is so arranged that the ten minute drum (19) is turned by one-sixth of a full turn every two revolutions of the drum (16).
